I knew that it's popular to put politician's faces on toilet paper (for instance, Amazon sells Obama toilet paper as well as Mitt Romney toilet paper), but I didn't realize that these kind of novelty products were being sold even back in World War I. [via Daily Mail]

A hot tub built into a 1969 Cadillac Coupe DeVille — both fully functioning. Its creators are taking it to the Bonneville Salt Flats next month to get it officially recognized as the world's fastest hot tub. More info here.

Back in 1996, two East German entrepreneurs came up with the idea of converting old telephone booths into shower stalls. They plumbed up two booths and sold them for 4000 marks each.

My German grandfather often used to say, "Ich bin kein Dukatenscheisser." (I don't s**t money.) But if he had this roll of toilet paper, he could have wiped with money. Or rather, gold.

It's 6-layer toilet paper embossed with 24-karat gold plate. It comes in 2 versions: either with the words 'Happy Birthday' or an Alpine rose embossed on it. Yours for only 178.50 Euros ($245, according to my desktop currency converter).
